Prince George gets shoved down a hill by his cousin Savannah

Just days after being shushed by his cousin Savannah Phillips at Trooping the Colour, poor Prince George has now ruthlessly been shoved down a hill.

Video has emerged of the future King trying to clamber up the grassy slope, before being pushed down by Savannah.

The four-year-old can then be seen being comforted by his mother Kate, while Savannah's mum, Autumn Phillips, gives her what looks like a stern talking to.

The future King of England just can't catch a break.

George, Charlotte and the Duchess of Cambridge joined Prince William on a trip to Gloucestershire, where he competed in the Maserati Royal Charity Polo Trophy. There was no sign of Prince Louis, who was born in April.

Earlier this week at this year's Trooping the Colour celebration, seven-year-old Savannah was visibly unimpressed with the four-year-old's rendition of the national anthem, and resorted to clapping her hand over his mouth to shut him up.

A tearful George was comforted by his mum.

Savannah is the daughter of Princess Anne's son Peter Phillips and is the Queen's eldest great-grandchild.
